RAIL-RETAINING Louvres.

Specification. of Letters latent.

Patented Jan. *7, 1919.

Application filed July 6 1918A Serial No. 243,540.

To all whom it may concern:

Be it known that 1, CHARLES KOBE, a citizen of the United States, residing at-Butte, in the county of Silver Bow and State of Montana, have invented .new and useful Improvements in Rail-Retaining Devices, of which the following is a. specification.

This invention relates to rail retaining devices, and the invention consists in the novel combination and arrangement of elements hereinafter described and claimed.

One obect is to provide in connection with a hollow metallic tie, a plurality of threaded elements mounted vertically thereimwith rail engaging devices each having a notched shank portion for engagement by one of the threaded elements.

In the drawings, a

Figure 1 is a plan view showing the retaining devices in position.

Fig. 2 is a side elevation.

Fig. 3 is a longitudinal section through a tie with the retaining devices in position.

Fig. 4 is a fragmentary horizontal section on the line 4-4 of Fig. 3.

Fig. 5 is a perspective view of the structure directly receiving the retaining elements for the rails.

Fig. 6 shows a tool for manipulating the caps of Figs. 7 and 8.

Figs. 9 to 11. are details described below. Figs. 10 and 11 representing slight modifications.

In constructing a tie especially adapted for use in connection with this rail retaining device, I preferably employ a plurality of channeled members 10 and 12 constituting the opposite sides of the tie, and a plurality of plates 14 and 15 constituting the top and bottom, respectively, of the tie. When assembled and secured with rivets along the free edges of the plates and the flanged por tions of the channels, the elements described form a tie of rectangular cross section and of the required length for the purpose intended;

The end members 16 and 17 comprise each a plate having flanged portions 18 on the edges thereof, these flanged portions being riveted to the ends of the plates and the channeled members.

A sufficient number of plates similarly formed extend transversely of the longitudinal members of the tie and intermediate of the ends thereof, these members being designated 20, 21, and 22. By means of this construction a tie thoroughly braced through out its length is formed and each portion of the tie is resilient to' a sufficient degree to provide for the vibration of the rail.

The rails are connected with the tie by means of certain novel railretaining devices now to be described. The elements termed spikes and corresponding with the usual form of engaging devices so far as function is concerned, are designated 25 and 26, being oppositely located as shown and extending through slotted portions 27 and 28 in the upper plate member 14 of the tie. These spikes are slidable vertically in guides 29 and are-provided with a series of teeth 30 adapted to be engaged by screws rotating in bearings and arranged alongside of the spikes. These screws are designated 31 and 32 and each is provided with an engaging portion 33 at itsupper end adapted tobe operated by means of a suitable tool provided with a socket correspondingly formed. Each engaging portion 33 is covered by means of a ca' p '34 adapted to preventthe entrance of water and foreignmaterial and being removable when'it is desired to rotate the screws for the purpose of adjusting the spikes or withdrawing the latter.

In Fig. 5 I have shown a block for supporting the screws 31 and 32 in suitable bearings 35, this block being provided with cylindrical bores 36 and 37 and with guides 38 for the accommodation of the spikes. The blocks may be formed of pressed steel or malleable steel and they are secured to the top plate 14 of the tie by means of bolts, rivets 14. Plates 39 retain the screws and spikes in place.

These plates are countersunk as shown in Fig. 3, and permit the passage therethrough of the axial members of the screws, and likewise permit of the passage of the spikes positioned, or to be positioned in guides 38 (see Fig. 4). Plates 39 bear against the screws in the manner illustrated.

A tool for operating or rotating the screws is shown in Fig. 6 and includes the socket portion 41 and at the opposite end a beveled portion 42 which may be employed as a screw driver for engaging the slot 43 of screw cap 34.

If the screw cap is provided with a squared end, the socket portion of the tool will en gage the cap. This form of cap is shown in Fig. 8 and is designated 48.

may form the tie with side members of I-beam construction as shown in Fig. 9. These elements are designated 49, and the locking devices for the spikes may be formed separately, each screw 50 being mounted in an independent block 51 and retaining a spike 52, as shown in Fig. 10. In Fig. 11 I have shown a member 55 with flanges on bothsides, which may be used for the ends or for the intermediate transverse braces.

The blocks shown in Figs. and (one form or the other being employed), are prefably placed within the body portion of the tie during the operation of assembling the parts of said body portion, and are secured to the upper plate 14 in the manner previously mentioned.

It will be understood that the screws are placed in position, and also the plates 39 for retaining them, before the blocks are inserted. The notches of the spikes and the upper ends of the screws so cooperate that proper engagement between these elements may be eflected'if the spikes are not inserted until the rail is to be secured. The spikes are screwed down by applying the tool of.

Fig. 6 to the element 33 of each screw, and the caps 34 are then screwed down and tend to prevent the loosening of screws 31, 32, and also serve to close the openings through which the axial elements of the screws pass.

The reverse of this operation in releasing the rail will be apparent.

What is claimed is:

1. In a device of the class described a spike having teeth formed on the edge thereof, a vertically mounted rotatable threaded mem'ber engaging the teeth, and means for supporting the spike and threaded member in operative position with reference to each other and with reference to the body portion of a tie.

2. In a device of the class described, a tie, a plurality of rotatable threaded members spaced apart and mounted vertically within the body of the tie, and a plurality of vertically movable rail engaging devices provided with teeth engaging the threads of the respective rotating members.

3. In a device of the class described, a hollow metallic tie, a block mounted therein near each end of the tie and provided with a plurality of chambers, a plurality of rotatable threaded members mounted within said chambers and a plurality of rail engaging devices each provided with notches on one side thereof, each of said rail engaging devices being operated by one of the rotatable threaded members.

In testimony whereof I ailix my signature.

CHARLES KOBE.
